How can I add custom CSS to a single page?

Questions
1

Hi,
I’m working on a page and I need to apply custom CSS only to this specific page.
I only have access to the Rich Text Editor, which removes tags and doesn’t allow advanced HTML.
I also don’t have access to edit the global site CSS or templates.

Is there any built-in way to: Add page-specific CSS, or Use a custom CSS field, Or enable a safe way to inject small CSS rules (media queries, margin adjustments) for this page only?

I only need styling control for a single page, not the entire site.

What’s the recommended way to achieve this?
-Umbraco version 10.8.7

Thanks!

If you only have an RTE that’s been correctly locked down to not let you add style tags you’re probably at a loss.

Does the site have Google Tag Manager - in the past I’ve injected css / js tags into certain pages. You would just create a rule for the url and fire the tag which inserts the css / js.
